Linux provides a powerful command-line interface for performing various tasks, including managing files and directories. One common task is to check the modification date of a file in a directory using the Bash terminal. In this blog post, we will explore how to accomplish this using a few simple commands.

Method 1: Using the ls Command

The ls command is a commonly used tool to list files and directories in Linux. By adding the -l option, we can retrieve detailed information about each file, including the modification date and time. Here’s an example:

ls -l path/to/file.txt

The output will show the modification date and time in the following format: yyyy-mm-dd hh:mm. You can find the modification information in the column that corresponds to the file name.

Method 2: Using the stat Command

The stat command allows us to gather detailed information about a file or directory. By specifying the %y or %Y format option, we can extract the modification date in a specific format. Here’s an example:

stat -c "%y" path/to/file.txt

The %y format option displays the last modification time in the format yyyy-mm-dd hh:mm:ss. If you want to extract only the date in the yyyy-mm-dd format, you can use %Y instead.

Method 3: Using the find Command

The find command is another powerful tool used to search for files and perform actions on them. By combining it with the -printf option, we can print the modification date of a file. Here’s an example:

find path/to -name "file.txt" -printf "%ty-%Tm-%Td"

In the above command, we specify the path to search (path/to in this example) and the name of the file we want to find (file.txt). The -printf option lets us format the output, in this case, %ty-%Tm-%Td which gives us the modification date in the format yy-mm-dd.

Conclusion

Checking the modification date of a file in a directory is an essential task in Linux system administration. Whether you prefer using the ls, stat, or find command, you can easily retrieve the modification information you need. Incorporate these commands into your workflow to effectively manage and monitor file changes in your Linux environment.
